In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may be embodied in many other forms than described herein and similarly modified by those skilled in the art without departing from the spirit of the invention, whereby the invention is not limited to the specific embodiments disclosed below.
Referring to fig. 1, fig. 1 shows a cooling system for an amphibious vehicle according to an embodiment of the present invention, specifically, the cooling system for an amphibious vehicle according to an embodiment includes an engine 10, an air cooling module 20 and a water cooling module 30, wherein the engine 10 is a power source of amphibious equipment, and the engine 10 releases a large amount of heat energy when operated. Further, the engine 10 is provided with a first cooling passage for circulation of a cooling medium, including but not limited to cooling water, through which heat energy released from the engine 10 is taken away by heat exchange with the engine 10.
The air cooling module 20 includes a first driving element 25, a fan 24 connected to the first driving element 25, and a second cooling passage 23 for circulating a cooling medium, the second cooling passage 23 being provided on an air outlet side of the fan 24, the second cooling passage 23 being in communication with the first cooling passage. The first driving member 25 is configured to drive the fan 24 to rotate, and the fan 24 is configured to convey air flowing at a high speed to the second cooling passage 23, and the air flowing at the high speed exchanges heat with the second cooling passage 23, thereby taking away heat energy of the cooling medium passing through the second cooling passage 23.
The water cooling module 30 includes a third cooling passage for circulation of a cooling medium, the third cooling passage being for immersion in an external water area, which refers to the area of water in which the amphibious vehicle is driven on water, so that water flowing through the external water area exchanges heat with the third cooling passage to take away thermal energy of the cooling medium passing through the third cooling passage. Further, the third cooling passage communicates with the second cooling passage 23 and the first cooling passage, so that the first cooling passage, the second cooling passage 23, and the third cooling passage constitute a closed circuit for circulation of a cooling medium.
Specifically, when the amphibious vehicle is driven on water, the engine 10 of the cooling system of the amphibious vehicle is started first, the engine 10 generates heat energy, and the cooling medium in the first cooling passage is driven to carry the heat energy to the second cooling passage 23. Meanwhile, the first driving member 25 drives the fan 24 to rotate, so that the air outlet side of the fan 24 generates air flowing at a high speed, and the air flowing at a high speed exchanges heat with the second cooling passage 23, thereby taking away a part of heat energy of the cooling medium passing through the second cooling passage 23. Then the cooling medium flows from the second cooling passage 23 to the third cooling passage, and as the third cooling passage is immersed in the external water area, the amphibious vehicle travels on the water so that the water in the external water area flows through the third cooling passage, and the flowing water exchanges heat with the third cooling passage, thereby further taking away the heat energy of the cooling medium passing through the third cooling passage. Finally, the cooled cooling medium returns from the third cooling passage to the first cooling passage, so that the cooled cooling medium exchanges heat with the engine 10 again and undergoes the next cooling circuit circulation. Further, when the amphibious vehicle is running on land, the power consumption of the engine 10 is reduced, and the engine 10 can be cooled by the air cooling module 20, which is not described herein.
The cooling system for the amphibious vehicle cools the cooling medium through the serial connection of the air cooling module 20 and the water cooling module 30, effectively improves the cooling efficiency of the cooling system, can reduce the energy consumption of the air cooling module 20, effectively reduces the volume and the weight of the air cooling module 20, further reduces the overall weight of the amphibious vehicle, and ensures the speed of the amphibious vehicle when the amphibious vehicle runs on water. In addition, the third cooling passage of the water cooling module 30 is immersed in the external water, and the flowing water in the external water is utilized to cool the cooling medium flowing through the third cooling passage, so that the advantage of the external environment is fully utilized, additional power driving is not needed, and the energy is further saved.

That is, the first cooling passage, the second cooling passage 23, and the third cooling passage are connected in series in this order according to the flow direction of the cooling medium. It should be noted that, in another embodiment, the cooling medium may flow from the first cooling passage through the third cooling passage and then through the second cooling passage 23, that is, in another embodiment, the cooling medium is cooled by air and then returns to the engine 10.
Further, the first driving member 25 is a hydraulic motor, and the cooling system for the amphibious vehicle further comprises a hydraulic system connected to the hydraulic motor, the hydraulic system being configured to rotate the hydraulic motor. The hydraulic motor is driven to rotate by the hydraulic system, and then drives the blades of the fan 24 to rotate, so that the cooling medium in the second cooling passage 23 can be cooled, and compared with the traditional mechanical driving, the hydraulic system of the hydraulically driven air cooling module 20 is flexible to install, and the installation position of the air cooling module 20 can be flexibly arranged, so that the installation space is further saved. Of course, it is understood that in another embodiment, the first driving member 25 may be a motor, and the fan 24 is driven to rotate by the first driving member 25.
Referring to fig. 1, in the present embodiment, the hydraulic system includes a hydraulic tank 42, a hydraulic pump 41, and a hydraulic line 43, and the hydraulic tank 42 is configured to store a hydraulic medium, which may be hydraulic oil, in particular.

The hydraulic line 43 is provided with a fourth inflow port 432 and a fourth outflow port 431, the fourth inflow port 432 communicates with the first input port, the fourth outflow port 431 communicates with the hydraulic tank 42, and the middle section of the hydraulic line 43 communicates with the hydraulic motor.
When the engine 10 is in operation, the hydraulic pump 41 is driven to operate, the hydraulic medium is pumped by the hydraulic pump 41 from the hydraulic tank 42 and is conveyed into the hydraulic pipeline 43, the hydraulic medium flows in the hydraulic pipeline 43 and drives the hydraulic motor to rotate, so that the hydraulic motor drives the fan 24 to rotate, and finally the hydraulic medium flows out of the fourth outflow port 431 of the hydraulic pipeline 43 and returns to the hydraulic tank 42 for recycling.
Further, after the hydraulic medium drives the hydraulic motor, a certain amount of heat is generated, if the hydraulic medium is not cooled and the heated hydraulic medium is directly returned to the hydraulic tank 42, the heat of the hydraulic medium is accumulated continuously along with the running of the amphibious vehicle, and finally, danger is liable to occur. Therefore, in the present embodiment, the cooling system for an amphibious vehicle further includes the fourth cooling passage 44 for circulation of the hydraulic medium, the fourth cooling passage 44 communicates with the hydraulic line 43, and the fourth cooling passage 44 communicates with the hydraulic line 43 at a position between the hydraulic motor reaching the fourth outflow port 431, the fourth cooling passage 44 is provided on the air outlet side of the fan 24 so that the hydraulic medium, when flowing out from the first driving member 25, first enters the fourth cooling passage 44, the high-speed flowing air is sent to the fourth cooling passage 44 by the fan 24, and the high-speed flowing air exchanges heat with the fourth cooling passage 44 to take away the heat energy of the hydraulic medium passing through the fourth cooling passage 44, and finally the cooled hydraulic medium returns to the hydraulic line 43 and flows into the hydraulic tank 42 from the fourth outflow port 431.
Preferably, the air cooling module 20 includes at least two fans 24, and the air outlet sides of the at least two fans 24 face the second cooling passage 23. For example, in the present embodiment, two fans 24 are provided, the two fans 24 are arranged side by side, each fan 24 is connected with one first driving member 25 for application, the two first driving members 25 are connected into a hydraulic pipeline 43 of a hydraulic system, and the two first driving members 25 are driven to rotate by a hydraulic medium in the hydraulic pipeline 43, so that the two fans 24 are driven to rotate.
Further, the cooling system of the amphibious vehicle further comprises a temperature sensor 51, the temperature sensor 51 is used for acquiring the temperature of the cooling medium, and the temperature of the cooling medium can be monitored in real time through the temperature sensor 51, so that the output power of the engine 10 is controlled, and the temperature of the cooling medium is ensured to be constant within a certain range. Preferably, the temperature sensor 51 may be disposed in the engine 10, the air cooling module 20, or the water cooling module 30, so as to obtain the temperature of the cooling medium at different positions, thereby realizing precise control of the temperature of the cooling medium.
Further, the cooling system of the amphibious vehicle further comprises a proportional valve 53 and a controller 52, wherein the proportional valve 53 is connected with the hydraulic pump 41, and the proportional valve 53 is used for adjusting the flow of the hydraulic pump 41. The controller 52 is electrically connected to the temperature sensor 51, and the controller 52 is electrically connected to the proportional valve 53, and the controller 52 is used for controlling the current voltage of the proportional valve 53 according to the temperature of the cooling medium, so as to adjust the flow rate of the hydraulic pump 41.
Specifically, when the temperature sensor 51 monitors that the temperature of the cooling medium is too high, the controller 52 increases the opening of the control valve by increasing the current voltage of the proportional valve 53, increases the flow rate of the hydraulic pump 41, and increases the rotation speed of the fan 24, thereby improving the cooling efficiency of the air cooling module 20 and accelerating the cooling of the cooling medium. Similarly, when the temperature sensor 51 monitors that the temperature of the cooling medium has fallen to a suitable temperature, the controller 52 reduces the output power of the engine 10 by reducing the current voltage of the proportional valve 53, so that the opening of the control valve is reduced, the flow of the hydraulic pump 41 is reduced, and the rotation speed of the fan 24 is reduced, thereby achieving the effect of saving energy.
